6 Claims.

This invention relates to new and useful improvements in a windowconstruction.

The inventionhas for an object the arrangement of a window constructionwhich is characterized by a means to constrain movement of the sash orsashes in the act of sliding and located either on the sash or sashes ofthe window and acting against the jamb, or on the jamb and actingagainst the sash or sashes.

It is a still further object of this invention to arrange a plurality ofweather flanges on the sashes and acting in non-contacting tracks orguideways in the jamb, ortoarrange the flange or flanges on the jamb andacting in non-contacting tracks or guideways on the sash or sashes,

in a manner so that the flanges practically float within the guidewaysdue tothe constraining a'otion accomplished by such means as rollers orthe like. d a vIt is a still further object of this invention to arrangecertain of said rollers in a manner to prevent transverse motion of thesash or sashes. Further, it is an object to arrange the rollersso as toprevent the flanges and tracks before mentioned from frictionallyengaging each other, accomplishing instead a floating construction.

A still further object of this invention is to arrange the rollers whenlocated uponthe jamb in a manner so that in all positions of the sash orsashes, the latter element or elements always contact therewith so as tomake it possible to move the sashes through their entire path of motionand have the roller contacts at all times. For simplicity, inrepresentation only one set of rollers at the central areas of thesashes is shown, whenthe latter elements are in their closed posi-'tions.

Furthermore as another object of this invention it is proposed toprovide baille flanges on the 40 sash capable of dividing a compartmentportion of the jambinto separate compartments, or baffle flanges on thejamb capable of dividing an air compartment in the sash or sashes intoseparate compartments so as to cause a number of reverses of airattempting to pass fromthe outside to the inside of the window or viceversa forming an efiicient seal.

As a still further object it is proposed to arrange the rollers to actagainst the baffle flanges mentioned in the previous paragraph forforming the floating arrangement of the weather flanges in theirguideways.

It is further proposed to arrange the rollers to occasionally actagainst the edges of the bafiie flanges so as to limit lateral motion ofthe the provision of slight transverse movement of sashes whichwouldcause the edges of the weather flanges to engage against the insides oftheir guideways and thus cause friction. Further, any combination ofrollers may beused, that is, the rollers may be arranged on one of thesides of the bafile flanges only, or on both of the sides of the baiileflanges, or any combination of the sides and the edges of the baffieflanges.

It may be well to state here that while theinvention has beenillustrated and described as particularly applied to metal windows, thisis not intended as a limitation since it may be similarly applied toother types of windows such as wood or wood with metal coverings or thelike. ,Another arrangement would be the applicationv of metallic sashstrips upon the sides of wooden sashes in cases where the invention isto be applied to wooden windows. 7 Another one of the objects of thisinvention is the rollers so as to allow drawing together of inner andouter sashes in the closed positions of the latter elements in theaction of fastening the sashes together as is conventional construeion.

Instead of rollers other means such as sliding surfaces may be used andthe friction in such cases will be small since the contacting faces maybe made small.

A still further object of this invention is the provision of a windowconstruction which is of simple durable construction, dependable in useand efficient in action, and which can be manufactured and sold at areasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had tothe following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.95

Fig. 4 is a fragmentary perspective View of a 1 portion of the baffleflange seen as though looking in the direction of the line 4-4 of Fig.2.

Fig. 5 is a view similar to a portion of Fig 2, but illustrating amodified construction.

The window construction comprises a window jamb member 10 for mountingwithin masonry 11 or in any other manner upon a building. A weight box12 is associated with the jamb 10 for receiving couunterweights 13 usedin counterbalancing the sashes of the window. A division plate 14 withinthe weight box 12 serves to divide the'weight box into compartments soas to separate the paths of the weights. In Fig. 1 a window frame 15 isillustrated which is provided with a double hung window having'a-n outersash 16 and an inner sash 17. While a double hung window has beendisclosed, the invention can be equally applied to other types ofwindows and to windows that do not necessarily move in the vertical.

The sash members 16 and l7-are slidably arranged within the window frameso as to coact with the jambs 10 in their non-contacting sliding action.Groups of rollers 18 are shown in Fig. 1.

arranged within the jamb member at the central portions of the sasheswhen the sashes are in their closed positions for the purpose ofaccomplishing slidable supporting of the sashes. In Figs. .1 and 2 oneembodiment of the invention has been disclosed, in which the groups ofrollers 18 are arranged in the jamb.

A long compartment 19 is provided for each of the sashes and extends thefull length of the jamb. This compartment is formed by the attachment ofa metallic or other member upon the jamb and is provided with a frontslot 20 extending its full length. A baflle flange 21 projects from theWindow sash and engages into the compartment through the front slot 20.A bracket 22 35' isfixed in the longitudinal compartment 19 and servesto support the group of rollers 18 in a fashion so that the baiiie 21 isefliciently supported and constrained from transverse movement.

' The group of rollers 18 comprises an edge roller 23 rotatively mountedin the bracket 22 and lo-' cated so as to guide the edge of the baffleflange 21. The group 18 also includes a pair of opposite rollers 24rotatively supported in the bracket 22 and engaging upon opposite-facesof the baflle flange 21 so as to slidably suppoit the latter element. Aplurality of weather flanges 25 project from the sashes and engagewithout contacting in tracks or guideways '26 supported on the jamb 10.The rollers 24 should be so designed and positioned as to hold theweather flanges 25 from contacting with the sides of the guideways 26while sliding, and the roller 23 should be so arranged as to make itimpossible for the edges of the weather flanges 25 from engaging againstthe inside of the guideways 26. The weather flanges 25 together with thebaflie flange 21 serve to form a practical weathertight arrangement eventhough the parts do not form contacting sliding fits in that they arearrangedto cause many reverses of the air in its travel.

For example, the passage of air may be traced from the outside at thepoint 27 into the guideway 26, then travel must reverse so astodischarge within the compartment 28 formed by one of the weather flanges25 and the bafile 21.

Next the current must reverse again and pass through the longitudinalopening 20 and into the longitudinal compartment 19. Another reversethen must take place in the air to travel along the other side of thebaiile flange 21 out through the longitudinal opening 20 and then bewithin the compartment 29 formed by the other of the weather flanges 25and the baffle flange. The current then must continue into the guideway26 and then reverse again out from the guideway.

By this time the travel of the air has been so resisted that it ispractically nil. The sashes include panes of glasses 30 held in place bymetallic binding strips 31 on opposite sides thereof. I

It is conventional construction to latch the sashes together when in theclosed position by a fastener which has a cam surface tending to drawthe sashes together. As shown on the drawings, this-fastener comprises acup 32 pivotally supported to swing in the horizontal and having a camsurface 33 and being mounted upon one of the sashes. This cup iscoactable with a hook element-34 fixed upon the other of the sashes ina'manner so that the cam may be turned to cause engagement with the hookand upon turning to draw the sashes together. A handle 35 projects fromthe member 32 to allow manual turning. From this brief description it isthought that the fastener can be recognized, since it is of conventionalconstruction generally used. In order to allow-the window sashes tobedrawn together'by the fastener, certain resiliency must be provided inthe vicinity of the group of rollers 18. For this purpose the baflieflange 21 is formed with cuts 36 located above and below the points ofcontact of the rollers 24 with the bafile flange 21. The small sectionof the bafile flange between the cuts 36 as shown in Fig. 4 necessarilyhas a large degree of flexibility and this allows flexing when thesashes are drawn together.

In Fig. 5 a modified construction of the invention has been disclosed inwhich the main difference is that the constraining mechanism is carriedby the sash member instead of by the jamb member. In this figure thejamb is indicated by reference numeral 38 and is shown supported uponmasonry 39. A weight box 40 is usedin conjunction with the jamb 38. Aweight 41 is arranged within the weight box for counterbalancing thesash. The sash 42 is shown carrying a bracket 43 which supports rollers44,- 45 and 46. A member 47 is attached upon the jamb 38 and has aprojecting baffle flange 48. The member 47 also has weather flanges 49.

The sash member is provided with tracks or guideways 50 into which theweather flanges 49 co-act. 'I'he rollers 44 and 46 act against theopposite sides of the baiile flange 48 so as to slidably support thesash in a manner that the guideways 50 may not touch the weather flanges49. The roller 45 is located along the edge of the baflie flange 48 forthe purpose of preventing the sash from moving laterally in a manner inwhich the bases of the guideways 50 would engage against the edges ofthe weather flanges 49. The operation of this form is substantiallyidentical with the preferred form as it relates to the passage of airfrom the front to the rear of the sash and as it regards the slidablesupporting of the sash for the elimination of friction. a

From the description the operation will be clear, but it may be best toamplify upon the advantages of the invention. It should be noticed thatthe provision of the baffle flange forms a strong structure sothat it ispossibleto use narrower sections for the sashes or the jambs withoutsacrificing strength. The introduction of the baflie plates serves toadd additional passages for the air to cause a greater numberofreversesand add to the efliciency of the weather seal of the window.Furthermore, the provision of the bafiie flange which acts against therollers to slidably guide the sash serves to separate the weatheringfunction lie from the tracking function of the sash. By this it is meantthat contacts between the weather flanges and the track or guidewaystherefor are not necessary.

The floating co-action eliminates sliding contacts of flat pieces.Furthermore, allowance is made for the movement of the sash due toexpansion and contraction and inaccuracies in manufacturing. Tolerancesare also provided for accommodating different sizes and improving theweather stripping of the window and incidentally eliminating rattling inthat the rollers act firmly and unyieldingly against the baffle flangeor the like. The rollers may be set at predetermined and accuratepositions and then maintain the correct spacing of the sash relative tothe jamb so that the weather flanges properly float within theguideways. The invention is not restricted to a single hung, double hungor any other type of window. Warping and inaccurate sizes of parts willnot produce binding. The rollers are used in group and may be accuratelyassembled and machined in casting, or may be individually appliedaccording to various designs.

Provision is made so that cooperating surfaces and cooperating edges andsurfaces can maintain definite relation without touching, except at theroller points. This is accomplished by projecting the peripheries of thewheels slightly in advance of the surface or edge, or by directlycontacting the rollers with the edge or surface. The provision of thebearing contact of the rollers upon the balile flanges serves toeliminate rattling of the sashes without the necessity of anti-rattlingdevices. Friction according to current practice is reduced by greaterspacing of the weather flanges from the sides of the guideways and theconsequent greater loose fitting. In spite of the greater spacing andlooser fittings, rattling is not present and the weather proofingincreased.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit orthe scope of the appended claims.
